Abstract

Cavity flows arise in many aerospace applications, such as wheel wells, weapons bays, and other fuselage openings for telescopes and sensors. The turbulent mixing of a cross-flow jet in a cavity is computationally studied using the large-eddy simulation (LES) and improved delayed detached eddy simulation (IDDES) approaches. The study concerns the direct relation between feedback acoustic waves and shedding vortex at leading lip. The study reveals that IDDES is a promising approach for the computation of highly turbulent flows.
